Abstract
GT block at present, injection-production well pattern and water injection mode has basically met the needs of
oil field development. In order to study the suitable surfactant flooding system of domestic carboxylate for ASP flooding
in Daqing oil field, for the first time, in GT block we carry out domestic oleic acid carboxylate surfactant applied to field
experiment of asp flooding. The indoor experiment and field test show that, test obtained the effect that oil is increased
and water precipitation is reduced. In addition, great changes have taken place in ion of produced fluid. And
emulsification happened, but emulsification extent without added. This experiment is the first time to apply oleic acid
surfactant in Daqing oil field. Therefore the result and analysis produce a positive effect on alkali-surfactant-polymer
flooding in Daqing oil field.
